About The Position

Revolution Medicines is a late-stage clinical oncology company developing novel targeted therapies for patients with RAS-addicted cancers. The company’s R&D pipeline comprises RAS(ON) inhibitors designed to suppress diverse oncogenic variants of RAS proteins. The company’s RAS(ON) inhibitors daraxonrasib (RMC-6236), a RAS(ON) multi-selective inhibitor; elironrasib (RMC-6291), a RAS(ON) G12C-selective inhibitor; zoldonrasib (RMC-9805), a RAS(ON) G12D-selective inhibitor; and RMC-5127, a RAS(ON) G12V-selective inhibitor, are currently in clinical development. As a new member of the Revolution Medicines team, you will join other outstanding professionals in a tireless commitment to patients with cancers harboring mutations in the RAS signaling pathway. The Opportunity: We are seeking an experienced senior toxicologist, who combines scientific excellence with strategic leadership, for our Toxicology group within the Nonclinical Development and Clinical Pharmacology (NDCP) Department, to work in close collaboration with Research and Development colleagues on new and ongoing portfolio projects. Working within a highly collaborative, cross-functional organization, this role provides toxicology leadership from early research through all stages of clinical development, ensuring that safety assessments enable informed development decisions and global regulatory filings.
